Lovende resultater for målrettet
behandling med entrectinib hos pasienter med NTRK-mutasjon positive krefttyper
• Entrectinib er en ny tyrosinkinasehemmer som er utviklet for å ha effekt i kreftsvulster med ROS1- og NTRK-mutasjoner. Molekylet er også designet for å ha effekt i sentralnervesystemet, da
hjernemetastaser er en stor klinisk utfordring for kreft med disse spesifikke genfeilene.
• Data som ble presentert i dag på kongressen til European Society for Medical Oncology (ESMO) i München var en samleanalyse av
tre studier med entrectinib som inkluderte 54 pasienter med diverse krefttyper med NTRK-mutasjoner (blant annet lungekreft og sarkomer) og viste at 57,4% av pasientene hadde en klinisk relevant respons av behandling med entrectinib. Median varighet av denne responsen var 10,4 måneder.
• Et viktig funn var at entrectinib også viste effekt i over halvparten av pasienter med spredning av kreft til hjernen (54,5%).
• Sikkerhetsprofilen av entrectinib var som forventet og håndterbar i klinisk praksis.
• NTRK-mutasjoner er sjelden (<1%) og det finnes per i dag ingen godkjente behandlinger mot krefttyper med denne genfeilen i Norge.
Basel, 21 October 2018 - Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced results from an integrated analysis of the pivotal phase II STARTRK-2, phase I STARTRK-1 and phase I ALKA-372-001 trials that
showed the investigational personalised medicine entrectinib shrank tumours (objective response rate; ORR) in more than half (57.4%) of people with
neurotrophic tropomyosin receptor kinase (NTRK) fusion-positive solid tumours. Objective responses to entrectinib were seen across ten different solid tumour types (median duration of response [DOR]=10.4 months), including in people with and without central nervous system (CNS)
metastases at baseline. [1] Importantly, entrectinib shrank tumours that had spread to the brain in over half of people (intracranial response; IC
ORR=54.5%), with more than a quarter of these people having a complete response. [1] The safety profile of entrectinib was consistent with that seen in previous analyses. [1]
"These data demonstrate the potential of entrectinib to treat a range of difficult-to-treat and rare cancers regardless of their site of origin," said Sandra Horning, MD, Roche's Chief Medical Officer and Head of Global
Product Development. "Entrectinib has the potential to redefine personalised medicine, which can utilize tests such as next-generation sequencing, to find the right treatment for each individual patient. People with NTRK fusion- positive solid tumours need more options, and we look forward to working with health authorities to bring this potential treatment to patients as soon as possible."
Roche is leveraging its expertise in developing personalised medicines and advanced diagnostics, in conjunction with Foundation Medicine, to develop a
novel diagnostics approach using next-generation sequencing that will help identify people with NTRK gene fusions likely to benefit from entrectinib.
[2;3]
Entrectinib has been granted Breakthrough Therapy Designation (BTD) by the US Food and Drug Administration (FDA); Priority Medicines (PRIME)
designation by the European Medicines Agency (EMA); and Sakigake designation by the Japanese health authorities for the treatment of NTRK fusion-positive, locally advanced or metastatic solid tumours in adult and paediatric patients who have either progressed following prior therapies or have no acceptable standard therapies. [4] These designations are reserved for medicines that demonstrate substantial improvements over existing therapies or where there are unmet medical needs.
These NTRK fusion-positive results will be presented at the European Society for Medical Oncology (ESMO) 2018 Congress in Munich, Germany on 21
October 2018, 11:24-11:36 am CEST (LBA17). Follow Roche on Twitter via
@Roche and keep up to date with ESMO 2018 congress news and updates by using the hashtag #ESMO2018.
Roche also recently presented positive results at the IASLC 19th World Conference on Lung Cancer (WCLC) that showed entrectinib shrank tumours (ORR) in 77.4% of people with locally advanced or metastatic ROS1-positive non-small cell lung cancer (NSCLC). [5] In addition, entrectinib demonstrated a durable response of more than two years (DOR=24.6 months). [5]
Importantly, entrectinib was shown to shrink tumours in more than half of people with cancer in the CNS (IC ORR=55.0%).[5] The safety profile of entrectinib was consistent with that seen in previous analyses. [5]
Roche plans to submit results from these integrated analyses to global health authorities for the treatment of NTRK fusion-positive solid tumours and
ROS1-positive NSCLC.
About the integrated analysis
The integrated analysis included data from 54 people with locally advanced or metastatic NTRK fusion-positive solid tumours (10 tumour types, >19 histopathologies) from the phase II STARTRK- 2, phase I STARTRK-1 and phase I ALKA-372-001 trials.[1] The studies enrolled people across 15 countries and more than 150 clinical trial sites. Tumour types evaluated in
the studies to date included breast, cholangiocarcinoma, colorectal, gynaecological, neuroendocrine, non-small cell lung, salivary gland, pancreatic, sarcoma and thyroid cancers.
• STARTRK-2 is a phase II, global, multicentre, open-label basket study in people with solid tumours that harbour an NTRK1/2/3, ROS1 or ALK-positive gene fusion. [6] The primary endpoint is ORR and DOR is a secondary endpoint. [6] Other secondary
outcome measures include time to response, clinical benefit rate, intracranial tumour response, progression-free survival (PFS), CNS PFS and overall survival (OS). [6]
• STARTRK-1 is a phase I, multicentre, open-label dose escalation study of a daily continuous dosing schedule in people with solid tumours with NTRK1/2/3, ROS1 or ALK gene fusions in the US and South Korea. [7] The trial assessed the safety and tolerability of entrectinib via a standard dose escalation scheme and
determined the recommended phase II dose. [7]
• ALKA-372-001 is a phase I, multicentre, open-label dose escalation study of an intermittent and continuous entrectinib dosing schedule in people with advanced or metastatic solid tumours with TrkA/B/C, ROS1 or ALK gene fusions in Italy. [8]
Overall, entrectinib was well tolerated and the majority of adverse events were Grade 1-2, reversible, and managed with treatment interruption or dose reduction. [1] Treatment-related adverse events leading to discontinuation occurred in 3.9% of patients. [1] The most common treatment-related adverse events were altered sense of taste (dysgeusia), fatigue, and dizziness.[1]
About entrectinib
Entrectinib (RXDX-101) is an investigational, oral medicine in development for the treatment of locally advanced or metastatic solid tumours that harbour NTRK1/2/3 or ROS1 gene fusions. It is a selective, CNS-active tyrosine kinase inhibitor designed to inhibit the kinase activity of the TRK A/B/C and ROS1 proteins, whose activating fusions drive proliferation in certain types of cancer. [2;3] Entrectinib can block ROS1 and NTRK kinase activity and may result in the death of cancer cells with ROS1 or NTRK gene fusions. [2;3] Entrectinib is being investigated across a range of solid tumour types, including breast, cholangiocarcinoma, colorectal, gynaecological, neuroendocrine, non-small cell lung, salivary gland, pancreatic, sarcoma and
thyroid cancers. [6-8]
Entrectinib has been granted Breakthrough Therapy Designation (BTD) by the US Food and Drug Administration (FDA); Priority Medicines (PRIME)
designation by the European Medicines Agency (EMA); and Sakigake designation by the Japanese health authorities for the treatment of NTRK fusion-positive, locally advanced or metastatic solid tumours in adult and paediatric patients who have either progressed following prior therapies or have no acceptable standard therapies. [4]
About NTRK gene fusions
Neurotrophic tyrosine receptor kinase (NTRK) fusion-positive cancer occurs when the NTRK1/2/3 genes fuse with other genes, resulting in altered TRK proteins (TrKA/TrKB/TrKC) that can activate signalling pathways involved in proliferation of certain types of cancer. NTRK gene fusions are tumour- agnostic, meaning they are present in tumours irrespective of site of origin, and have been identified a broad range of solid tumour types, including breast, cholangiocarcinoma, colorectal, gynaecological, neuroendocrine, non- small cell lung, salivary gland, pancreatic, sarcoma and thyroid cancers. [1]
There is a high unmet medical need for treatments for people with life- threatening NTRK fusion-positive tumours.
